al M14 f g8@ of the grooves e e and the guides r r, the lat ter permitting them to pass, and then being` immediately forced back to their former position by the springs j (see Fig. 1, dotted line) pressing against the pegs o, screwed in the under surface of such guides, which pegs slide in the grooves h in the piates fastened under the grooves e e. The hooksE E slide in the guides l, Figs. 1 and S, at n', secured to the plate D on the block A, and have in their lower ends another peg, p, screwed in the up per surface of such hook, which slides in the grooves s in the lower ends of the slides F, Figs. 3 and 4, which slides rest in the guides Z, before referred to, at n, and in the guides m, Figs. 1 and 9, and are held in place by ties, Fig. 10 showing the one to be placed on the oblique guides l l, Fig. 8, the ties to be placed on the guidcsm, Fig.9, being plain oblong bars of metal, having each two holes for the insertion of the rods 7c and 7.x', which ties are secured by nuts screwing on the screw-rods 1 of such guides, and in the rectangula grooves q of the slides F move the drivers G, Figs. 2 and 6, connected by bolts and nuts with the crosshead t, ofthe arms H, said drivers movi ng freely between a central support, Fig. 12, and e and i0, Fig. 2, constructed of two piecesa base support, e, and top stand,w-soldered together, and standards L L, Figs. 1 and 2, fastened to the plate D on the block A on bolts which I insert through holes u in such standards, drivers, and central support and secure with nuts on the outside and the other cross-heads, t', of the arms H, connect with the pedal-arms I, to which are attached the pedals J J, each of which pedal-arms turns on a pin, ir, Fig. 2, between two supports, y, riveted to plates e', let into the blocl; A and fastened with screws, the supports being iixed in the rectangular apertures g in said block. Upon pressing with the foot on one of the pedals J, attached to the pedalarms 1, these pull with them the arms H, which connect with the drivers G, these moving the slides F, and the latter moving the hooks E, which turn the wheel B in the way above described. The foot being then raised, the several parts will be forced bach to their former position by the reciprocating pressure of two strong spiral springs, K, Figs. 1 and 2, pressing against the pedal-arms I. The dotted lines seen over the latter in Fig. 1 merely illustrate the movements made by such pedal-arms, the dotted lines representing them as they appear when held by the said impetus of the spiral springs K, and the real illustrations representing them as they appear when the pedals J are pressed upon with the foot.

In Table Il, M and M, Figs. 1 and 3, are two bevel-wheels gearing in each other, the upper one, M, revolving on the shaft F, Figs. 2 and 3, forming the axis of the wheel O in the metal box N, to which it is fastened by a screw, c, Fig. 1, and the lower bevel-wheel, M', revolving in a circular bearing in the horizontal plate T, being fastened on such plate by a ring, r,

secured with screws on its nave under said plate. 0n the surface of the wheel O are turned six grooves, b, in which l solder six sets of cogs, c, one above the other, following in regular rotation, which cogs gear in thel teeth of the pinions R, which turn on a rod,o,aflixed in the bottom plate, d, oi`- the box N, the upper end of which rod passes through the cover d of said box, its end being threaded for the reception of a nut by which it is secured, and in the pinion It, are screwed the hinges ,l' with their wiresj and jh Between each ofthe pinions R. the bottoni plate, d', and cover d ci" the box N, previously mentioned, and the wheel O is a washer, p, to prevent the parts from rubbing` against each other.

The, hinges j', 1 make of thin sheet metal bent in the form of an inverted U, in one end of which l solder a piece ot' metal, It, and in this fasten a screw-rod, a, as seen in Fig. 4., which screws in the pinions 1t, as aforesaid, and at t', I a pin, on which is hinged a short piece ot' wire, s, on which is soldered ajoint, g, and in this I fasten the two l'lat wiresj and j', between which the leaves of the music are. to be inserted,which can be conveniently donc by bending all the wires down and then inserting the leaves of the music between them one by one.

The box N is supported by four standards or legs, c and c, (see Fig. 3,) the height ot' which and the breadth of the nave or hub ot' the bevel-wheel M may be diminished with adi'antage to the dotted line y g, this lessening the space occupied by the machine.

Z and m, Fig. 2, are six litt-le posts, on which rests the cover d, titting in a groove in thc casing oi' the box N, the four posts Z passing through holes in such cover, which is secured by screws crewing in the screw-holes 7c of the posts in., the axis l oli' the wheel projecting through and revolving in a central hole in such cover. The posts l and m, above rcljerred to, are afiixed in the bottoni plate, d, of the said box N.

The upper machine is supported in the manner shown by the dotted line in Fig. 3, the note rack being placed just above the machine. Having aflixed the upper machine, it is then connected by a rod, S, Figs. 1 and 3, passing through the center oi" the lower bevel-wheel, M', and secured by a screw, u, screwing in a screw-hole in such rod, which connects with the shaft C of the wheel B of the lower inachine, Table l, by means of a coupler, (seen in Figs. 2 and 11,) and the whole machine is then in working order, each pressure of the foot upon one ot' the pedals J J ot' the lower machine causing the wheel B to rotate either to the right or left, which movement is conimunicated by means ofthe vertical rod S and the bevel-gearing M and M' to the wheel 0 of the upper machine, and this turns the pinions 1t, to which are attached the hinges j' and wires j and j, the latter turning the leaves of the music inserted between them.

eeaoee o My invention is applicable to anyY ordinary; imtestantl, anal especially to pianos. When afiixefl to the latter, however, a hole must be drilled through the case for the insertion oi' the rod S, hereinbei'ore described, the upper machine bring` adjusted so as t0 make the noteraol; come just above the box N, and the lower machine b'eing` affixed to a lyre or other suitaable support, similar to that to which the ped als of a pieno are fastened, about one inch, but not less, above the ground. The number or' leaf-miniers might also be increased, if ciesirable, to ten, (this being;` about the highest average number of leaves niet with in a piece oi' niusie,) which ma;v be (lone by increasing` the number of bolts d of the Wheel B to that number, and diminishing` the size of the grooves c e on either side of said Wheel to about twothirds oi" their original length of the pedal movement, and by increasing,` the number of v,grooves b and sets of oogs o of the Wheel 0 and pinions R, with their appurtenances, also 'from six to ten of the upper or leafturning` mechanism; but then the size oi' said grooves b, sets of cegs o, and pinion R should be diminished so as not io require enlargement of the metal box N ot' said upper mechanism.

New, what I claim as my invention, and desire to secure by Letters Patent, is-

rEhe combination or' the pedal movement or L lower part oi' my machine, consisting` of a rotating wheel, B, hooks E, the movements of the latter being guided by the grooves e e and movable guides r i', slides F, drivers G, arms H, and. pedal-arms I, on which are pedals J, the said hooks E oat-ching against one of the bolts el of the said Wheel B and causing it to turn with the upper or leaf-turning mechanism, the motion of the said Wheel B being` transmitted by the vertical rod S and the bevel-groanng` M and M to the Wheel 0, on

which are coge c, gearing in the teeth oi' the pinions E, to which are fastened the hingesj' and Wiresjj, between which the music-leaves are to be inserted, all as hereinbei'ore substantiall)v described,
